I know I know it says premium unleaded gas all over the place. Gas prices are getting pretty high and its not much fun...I have used both premium and regular gas and see no difference. it runs perfect on the low octane. I hate to be cheap on stuff like this but is it nreally neccessary to keep from having problems or only if I have problems already with ping and so forth?
